DOKIO 300W Portable Foldable Solar Panel Kit — 12V Battery Charging, PWM Controller & Dual USB, Lightweight Foldable Design

This kit brings a high-output solar array in a packable, easy-to-carry format designed for outdoor use. The panels fold down to a slim profile for transport or storage, include a separate PWM controller for safer battery charging, and provide dual USB ports for phones and small electronics. A 3-meter cable lets you place the array in direct sun while keeping your controller or power station in the shade for convenience and protection.

How does this solar kit perform in everyday outdoor use?

The DOKIO 300W panel produces strong daytime output suitable for topping up 12V batteries in RVs, trailers, and boats. Its low weight and slim folded size make it easy to move and mount, and the long cable keeps connections neat and cool.

• 300 watts of peak panel capacity for efficient charging in good sunlight
• Weighs 15.3 lb for simple one-person handling
• Folds to 20 × 38 × 1.1 in to fit closets, racks, or vehicle storage
• 9.84 ft (3 m) cable to separate panel placement from the controller or power station

What safety and charging protections are included?

The kit includes a standalone PWM charge controller that protects your 12V battery from common issues like reverse polarity and overcharging. Because the controller is separate, it’s easy to replace or upgrade if you need a more advanced MPPT unit later.

• PWM controller guards against reverse connection, overcharge, overload, and short-circuit
• Separate controller simplifies troubleshooting and future upgrades
• Durable connectors and cable routing reduce stress at attachment points

Will this panel work with my power station or battery system?

Many portable power stations limit the maximum solar input (for example, 150–200W), so a 300W panel may be capped by that device’s circuitry. The panel will still operate normally; check your power station’s input limits or contact us before buying to confirm compatibility.

• Panel can deliver up to 300W in ideal sun, but device input caps may limit actual charge rate
• Compatible with 12V batteries when connected through the included PWM controller
• Contact customer support if you’re unsure about your power station’s solar input rating

What convenience features help during trips or emergencies?

The DOKIO kit is built for portability and quick setup: it is lightweight, folds flat for storage, and includes USB outputs for charging phones and small devices. In bright sunlight, USB ports can supply emergency power even without a battery, though output can vary with conditions.

• Dual USB ports for charging phones, lights, and small appliances from a 12V battery
• USB output possible from the panel in direct sun for short-term emergency use
• Slim foldable design and carryable weight make it travel-friendly for RVs and campers

Who is this for: Outdoor enthusiasts, RV and camper owners, vanlifers, boaters, and anyone who wants a portable solar source for 12V battery charging or emergency power. It’s especially useful for users who want a lightweight, easy-to-store panel with basic electronic protections and the flexibility to upgrade the controller later. If you rely on a specific power station, verify its solar input limit to ensure you get the charge rates you expect.
